Question about Emerson Televison & Video
A replacement power supply may be hard to find, however, they are usually not that difficult for an experienced technician to repair. The most common failure is a burned-out electrolytic capacitor (sometimes several go bad before the TV quits working). Common symptoms of a failing capacitor are trouble starting the TV - it may take several tries before it goes on and stays on, and occasional spontaneous shutdown. It gets worse until the set quits completely. Burned out capacitors are often easy to identify; the top will be domed instead of flat, and black or brown material may have seeped out of the top. See the photo below for a comparison of bad capacitors (domed tops marked with red) and a good flat-topped capacitor.
The missing light suggests you may have a failed standby power supply section. This could be a shorted transistor leading to a blown fuse and possible damage to other parts. My usual sources list the power supply for your model as out of stock, but ShopJimmy has repair kits for some versions (see link below) with this problem. At $13, they are getting a substantial premium over the cost of parts from component suppliers, but you also get instructions on which parts to change and save the hassle of looking up and ordering each part. (Soldering skills and anti-static protection knowledge required.)

Note: You can save some money on labor charges by removing the back of the TV. (Keep track of where the screws go; there may be several types, and check carefully around the connector jacks for screws. Any screw marked with a triangle or arrow must be removed to take off the back, but not all may be marked this way.) Be sure to unplug the TV and wait at least 30 minutes before working on it; the input power capacitor may be charged to power line voltage and can give a nasty shock unless given time to discharge, especially if the circuit it feeds is disconnected by a blown fuse. Inspect the power supply for burned out capacitors, and compare the labels on the power supply with the numbers shown on the page linked above. If you have a digital multimeter, set it to 200 VDC and measure the voltage across Fuse F601. If you measure any voltage, the fuse is definitely blown. Don't replace it until the board is repaired (see the video in the link provided). If you don't measure any voltage, confirm the condition of the fuse by switching to the 200 Ohm range. A good fuse will read near zero Ohms, about the same as you would get touching the meter leads together. A bad fuse will read higher (the voltage measurement is to make sure you don't damage the meter by trying to measure the resistance of a part with voltage on it). If the fuse is blown, you probably need at least some of the parts in the repair kit. All of the parts in the kit except the resistor and fuse must be oriented the same way as the original; putting them in backwards can cause severe damage to the board. Prior electronic soldering experience is very highly recommended before attempting this repair yourself.
If you remove the power supply, be sure to handle the board only by the edges; do not touch any of the circuitry. Any static electricity charge on your fingers can damage the board, even if you don't feel a spark. Do not put it on or in any plastic bag or wrapper unless you know the bag is anti-static. If you must park the board somewhere, put it component side down so static buildup on the surface doesn't zap the circuitry.

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
